9k² = 225
k² = 225 : 9
k² = 25
k = -5 and k = 5 because :
(-5)² = (-5) * (-5) = 25

Payton has $20 to spend at the carnival Payton purchased 30 game tickets,2 slices of pizza, and one ice cream what number is equivalent to 20-0.45x20-1.75x2-2
Answer:
5.5
Step-by-step explanation:
The given operation is :
20 - 0.45 x 20 - 1.75 x 2 - 2
In the above algorithm contains more than one operations to be executed. Here we use the BODMAS rule that states that we first calculate the brackets then the orders, following multiplication or division and then at last addition or subtraction. Therefore,
20 - ( 0.45 x 20 ) - ( 1.75 x 2 ) - 2
= 20 - 9 - 3.5 - 2
= 11 - 3.5 - 2
= 7.5 - 2
= 5.5

List and explain 3 major differences between the Democratic party and the Republican party.
1. Fiscal differences
Democrats are usually pro-regulation, and Republicans are for a free market. However, both are pro-capitalism. Examples: 15 dollar minimum wage, Green New Deal
2. Social differences
Democrats tend to be more progressive in social view, meanwhile Republicans tend to want to stick to the traditions. This means LGBT, abortion BLM, etc.
3. Climate change
Most Democrats recognize that climate change is a problem (they wont do anything about it, but at least they recognize it I guess.) Most Republicans think that climate change is normal and there is nothing to do about it.
Are my answers for the conditional statement correct? I would just like to check them and if they're incorrect, could you let me know how to fix them? Thank you.
Statement: If I brush my teeth twice a day, then I will not get cavities.
Inverse: If I don't brush my teeth twice a day, then I will get cavities.
Truth Value: True
Converse: If I don't get cavities, then I am brushing my teeth twice a day.
Truth Value: True
Contrapositive: If I get cavities, then I am not brushing my teeth twice a day.
Truth Value: True
Statement: If p, then q
Inverse: If q, then p
Converse: If not p, then not q
Contrapositive: If not q, then not p.
We can see from the statement that p = brush teeth twice a day and q = not get cavities.
Thus:
Inverse: If I don't get cavities, then I brush my teeth twice a day. FALSE (for example, I might floss extra well instead. Brushing my teeth twice a day is not the only way to avoid cavities)
Converse: If I don't brush my teeth twice a day, then I get cavities. FALSE (for example, I might not eat a lot of sugar and thus I don't get cavities)
Contrapositive: If I get cavities, then I did not brush my teeth twice a day. TRUE
If this confuses you, try the example of p = cat and q = four legs. (i.e. the statement is If this is a cat, it has four legs). Try making the inverse, converse, and contrapositive, and see the truth of those statements.

Answer:
6. 12/13 7. 4/3
Step-by-step explanation:
6) cos = adj/hyp
opp ∠C = 5
adj ∠C = 36
hyp = 39
cosC = 36/39 = 12/13
7) tan = opp/adj
opp ∠C = 36
adj ∠C = 27
hyp = 45
tanX = 36/27 = 4/3
A 35-foot ladder is leaning against the side of a building and is positioned such that the base of the ladder is 21 feet from the base of the building. How far above the ground is the point where the ladder touches the building?
Answer:

An online furniture store sells chairs for $200 each and tables for $450 each. Every day, the store can ship a maximum of 26 pieces of furniture and must sell at least $6000 worth of chairs and tables. If xx represents the number of tables sold and yy represents the number of chairs sold, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
its 10
Step-by-step explanation:
Solution is x≈3.2 & y≈22.8
What is inequality?
An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
here, we have,
An online furniture store sells chairs for $200 each and tables for $450 each.
Every day, the store can ship a maximum of 26 pieces of furniture and must sell at least $6000 worth of chairs and tables.
Let, x represents the number of tables sold and y represents the number of chairs sold.
Then, the inequalities are,
we get,
$200y + $450x ≥ 6000
and, x+y≤26
Solving we get,
x≈3.2
y≈22.8
Hence, we get, Solution is x≈3.2 & y≈22.8
